Abstract

Die Erfindung betrifft eine Dichtungsanordnung insbesondere für Brennstoffeinspritzventile in Brennkraftmaschinen. Die Dichtungsanordnung besteht aus einer Ventilkugel und einem Ventilkörper, der einen konischen Ventilsitz für die Ventilkugel aufweist. Der konische Ventilsitz besitzt eine durch Schleifen bearbeitete Oberfläche. Erfindungsgemäß weist der Ventilsitz eine durch Feinschleifen (Finishbearbeitung) in die konische Fläche eingearbeitete, ringförmig umlaufende und im Längsschnitt kreisbogenförmige Sitzfläche für den Dichtsitz der Ventilkugel auf. Der Radius des die Sitzfläche bildenden Kreisbogens ist größer als der Radius der Ventilkugel. Die im Längsschnitt muldenförmige Vertiefung der Sitzfläche ist so bemessen, daß im Querschnitt gemessene Formabweichungen des konisch geschliffenen Ventilsitzes von der Kreisform zumindest im Scheitelbereich der kreisbogenförmigen Sitzfläche eliminiert sind.
